Chapter 4: Elements, Compounds, and Mixtures

Chemistry: What we hope to do in chemistry
We hope to experiment with different substances to determine changes in the mixtures.

Solution Lab

Purpose: will different compounds form solutions in water.

IV: Types of compound
· Copper Sulfate
· Zinc Oxide
· Sulfur
· Sodium Chloride
· Sucrose

DV: Ability to dissolve in water

Constants:
· Amount of water - 20
· Type of water
· Temperature of water
· Number of mixes - 5

Procedures:
1. Measure 20 ml of water.
2. Place a small amount (tip of lab scoop) of each compound in a separate test tube.
3. Add the water to the test tube and record observations.
4. Mix the test tube 5 times and record observations.

Compound	Observations	Dissolved
Copper Sulfate	Before: Crystals are staying at the bottom After: Dissolved	1. yes 2. Yes 3. Yes 4. Yes
Zinc Oxide	Before: Cloudy; White After: Cloudy; Opaque; White	1. Yes 2. No 3. No 4. No
Sulfer	Before: Floating on sides, top, bottom After: Stayed the same	1. No 2. No 3. No 4. No
Sodium Chloride	Before: Transparent, particles spread out After: Transparent, dissolved	1. Yes 2. Yes 3. Yes 4. Yes
Sucrose	Before: Transparent, particles at bottom After: Same	1. Yes 2. Yes 3. Yes 4.Yes
